“…Introduction Changes in spermatogenesis can be simulated through scrotal insulation (Brito et al, 2003;Fernandes et al, 2008); however, no information regarding the uses of Doppler ultrasound has been reported to evaluate the effect of scrotal insulation seminal parameters in bulls. Recently, researchers have suggested that the uses of IRT as a noninvasive method to assess scrotal insulation on sperm production in beef bulls is only desirable to evaluate scrotal gradient temperature at the time of insult removal (Menegassi et al, 2018).…”

“…Gabor et al (1998) determined PI in Holstein bulls and observed average and negative correlation (r = -0.48) with the proportion of live spermatozoa. However, Brito et al (2003), working with animals evaluated in the sperm recovery course after scrotal insulation, found positive correlation of PI with the percentage of major defects in Bos taurus taurus, and the white intensity of the ultrasound image presented association with the semen quality (r = -0.32) in relation to normal spermatozoa.…”

“…According to Abdel-Razek & Ali (2005), the testicular parenchyma of adult Taurus animals is homogeneous and with moderate echogenicity, while testicular parenchyma in young Nelore bulls, according to Cardilli et al (2009a;2010), is homogeneous and with low echogenicity. Corroborating the results of Abdel-Razek & Ali (2005), the average PI of the animals used in this study presented moderate echogenicity (95.7 and 94.0 for sound and unsound animals, respectively) in relation to the scale used (0 -255).…”

“…It is becoming an important biomedical tool for ultrasonographic image analysis [27,28]. In our study, the echodensity of the testes of YFPs were determined directly using software-based analyses of numerical PI.…”
